IT Cosmetics Bye Bye Under Eye Illumination Antiaging Concealer is your eight hours of sleep in a tube! A full coverage concealer designed to make your skin appear younger looking, this antiaging, skin loving formula is infused with hydrolyzed collagen; vitamins A, C, and E; hyaluronic acid; and peptides. It can be used to spot treat or as an allover foundation that doesn't look or feel like makeup at all.

Beautiful skin is so much more than coverage; it's also about the look of light; and IT Cosmetics(R) has captured the look of youthful and radiant-looking skin in this tube. Without the use of any glitter or shimmer, Drops of Light Technology will make it look as though light is pouring from your skin.

How do I use it: To use as an allover foundation, use the brush to smooth the concealer on your skin like a moisturizer. To target specific areas, squeeze a pin-size amount onto the back of your hand to warm, and then dip the flat side of the brush into the concealer and smooth directly onto your skin. Use the fluffy end of the brush to buff out your concealer for a natural-looking airbrushed finish.

Not easy to dispenseI was excited to try this, however I was disappointed at how difficult it was to squeeze a pin drop out of this very tiny tube. The tube itself has barley any product in it, and when you finally get some to the top of the dispenser too much comes out...and there's no way to put some back inside. I found this product works nicely when applied, but it's not worth the hassle or the money in my opinion. Need to design a better way to dispense this product.

Use as a foundationI have purchased both CC cream foundation and Bye Bye Lines foundation. Both were great but I needed something in between. I received this sample with my purchase and have used it as a foundation and it has been amazing!! Covers my full face with no crease or sliding/melting effect. I am purchasing a bottle now !

Best purchase everI really love this product. It truly highlights my eyes, covers up the dark circles under my eyes. It blends beautifully into my foundation.

Best IT product Ever for me.This product, Bye Bye undereye illumination with brush, is the best thing I have ever purchased from IT. The online instructions, video, is the best selling point. The IT rep shows how she uses it and more or less gave me to try what ever I thought right for myself. I do not really understand the brush. After taking the covers off, the buffing end keeps sliding down. One has to hold it with a finger tip not being used the whole time. Is this defective? At anyrate my face looks so much better with the dark red finally well concealed. I really wonder if this in the tub product is the same as the product as the in the small pot product by the same name and by IT.

Listen To Why I Love This!I am 52 and in the past few years have started to want a more natural looking face when doing my makeup. I’d love to just be able to do lips and eyes and a touch of blush, but my Rosacea also getting worse in recent years prevents me from doing that, so I have to fake it.
While not every IT product I’ve tried has worked for me, I am a regular user of the original Bye Bye Under Eye concealer in Medium, which exactly matches my skin undertone. I wanted something to subtly highlight the areas of my face like my Cupid’s bow, down the center of my nose and inner corners of my eyes, etc., so I ordered this in the lightest shade, and am so glad I did. It is exactly the same consistency of the original, so warming just a tad between two fingers and then gently tap it on is all you need to do. I did also test it under my eyes to see how well it worked, and they really looked naturally brighter despite the lighter shade.
I appreciate how the tube gives you the control and dispenses just a tiny bit so there’s no goopy waste. The brush is a wonderful bonus because I didn’t realize it but it’s like a travel brush with a buffer on one end and a smoothing flat brush on the other, with lid covers for both, so it doesn’t get dirty if I want to take it with me.
One note: I have found that all Bye Bye concealers work best when slightly warmed between your fingers and applied to well-moisturized skin. I have combo/dry/sensitive skin, so I do my major, heavy duty moisturizing at night, then use gel-consistency products during the day, and these concealers never look dry or cakey on me. Just lovely, natural-looking coverage when applied with some forethought.

A little thickI’m a bit torn with this product, I feel like it a little thick and is hard to blend. Definetly can’t use the brush, I needed and damp beauty blender. I keep trying it every so often but I’m just not super happy with it. As I mentioned in another review, I feel like the return policy and window is a little too narrow. I ordered quite a few products and it took a little time to give each of the products a fair chance before I knew for sure it wasn’t for me.

Consistency is thickMuch to thick, especially for delicate skin under the eye. I had to add a dab of moisturizer to the product to get it to move and to make it blendable. I found the coverage to be "average" and it felt thick and heavy under my eyes. My other concern is trying to remove it without tugging and pulling the delicate under eye skin. I will try the one in the pot as it has a creamy consistency and its in a glass jar which I prefer for all my products. I do use several it products on my 70 year old skin and love them. My favorite product for my super sensitive skin is the Confidence in a Cream. Hopefully they will make a super sized one and another one with SPF 50 for daytime.
